Toshiba 57H93 Problems...

I have a Toshiba 57H93 with a Scientific Atlanta 8300HD box from TimeWarner Cable Schenectady, NY. I have two problems that Time Warner andToshiba tech support have not been able to solve.

1- MY DVI input on the tv doesn't work with the SA8300HD2- TW transmits unscrambled cable analog channels and local HD anddigital channels. When the TV is connected directly to the cable coax(no cable box) the built in Toshiba tuners QAM, NTSC, ATSC go haywire(no audio, stuck on channels, or changes channels by itself).

Toshiba's answer to number 1: It's SA's fault. Use the componentoutputs only.

Toshiba's answer to number 2: a firmware upgrade above version 1.4.4 isneeded to solve this problem (maybe available sometime in the future)

I have a Toshiba 52 inch dlp HDTV with a Samsung HDTV satellite box. The DVI connection from the satellite box to the Toshiba is also inoperable on this set. I also contacted both parties and each blames the other. I do not have the time to run it down and the component connections work well enough. Sounds as if this is a common problem with Toshiba sets . . .
